Title: Method and device for receiving a phase-modulated light signal and for the detection of alignment errors
Inventor: WANDERNOTH BERNHARD
IPC: H04B10/60
Filed: 1998-08-17
Abstract: The directional reception of extremely weak light signals without diverting a portion of the signal light into separate detectors for the purpose of obtaining an alignment signal is caused by the arrangement of several detector means (X, Y) which, when unmodulated light is superimposed on them, generate electrical output variables (x1, x2, y1, y2) which, after they have been added in a network (I), result in an information signal which, when it is linked by multiplication with several difference signal (x, y) formed in the network (I), converts them into narrow-band signals, which reproduce an alignment error.

Inventor: BARANOV V I
IPC: H05H1/54
Filed: 1997-03-31
Abstract: A Hall effect plasma accelerator comprises an annular accelerating channel with a radial magnetic field applied across the channel between magnetic poles of opposite polarity. According to the invention, the magnetic poles are defined on bodies of material which are physically and magnetically separate. The accelerator may be used as a Hall effect thruster, producing a stream of ions deflected by appropriate adjustment of the magnetic fields, so as to produce thrust and steer a satellite or other vehicle. The channel, along which the ions are accelerated, is preferably flared outwardly at its open end to avoid erosion caused by the deflection. The adjustment of the magnetic fields is preferably achieved by dividing an outer magnetic pole, surrounding the channel, into separate sectors having individual coils. The invention allows greater freedom in selecting the dimensions of the thruster in general and of the magnetic system in particular, thereby improving thruster efficiency and allowing manufacture of thrusters having a wide variety of different shapes depending on the available space.

Abstract: Apparatus and methods useful to automate the task of locating a photograph or other image that is embedded within a larger image. An edge curve is found that approximates the perimeter of the embedded image and from the edge curve the rectangle of the embedded image, or a rectangle covering the embedded image, is calculated by processing density profiles of the edge curve taken along two axes. Both location and orientation of an embedded image can be calculated. The location of the four corners of a rectangular embedded image can be calculated, which enables automatic cropping and rotation of the embedded image, even if fewer than all four corners are visible. A rectangle covering the image can be calculated, including a rectangle aligned with the axes of a larger embedding image such as is created when scanning a small photograph on a flatbed scanner. The invention operates well on rectangular images, as well as on images having polygonal and other border shapes, such as circles and ellipses, including images with irregular shapes.
